To aZZwh-o'm it may concern: a

Be it known that ORRELL ASHTON, late of Swampscott, in the county of Essex and State of Massachusetts, deceased, invented certain Improvements in WVOrk Supports, of

'7 .which thefollowing description, in connection with the accompanying drawings, is a specification, like reference characters on the drawingsindicating like parts in the several figures. I

This invention relates to work positioning means for use in the manufacture of boots and shoes, and more particularly to means for positioning lasted shoes for the operation of various machines such for example, as

' fastening inserting machines.

-An object of the invention is to secure adequate freedom of movement of the shoe on its support in'presenting the same tothe workoperating instrumentality and to this end an important feature of the invention resides, in an improved work supporting,

movements in various directions by means of thezfreely movable abutment which maintains its operative face constantly in contact with the shoe at whatever angle the latter assumes in relation to the work operating instrumentality. Preferably the abutment is supported for adjustment vertically and also laterally by means entirely independent of the construction by which universal tipping movement of the abutment is secured This provides for adjusting the abutment'so as to position it properly against the shoe In another aspect, the invention resides an improved support for the toe portion of a lasted shoe so constructed and arranged that the shoe may be turned and tlpped and shifted in various directions during operations on the toe portion of the shoe as, for

instance, during the insertion of fastenings around the toe as reinforcing securing means. In the improved support a toe rest is-provided which is conveniently supported upon an extens on of the horn of the fastening inserting machine through means providing ior tipping movement of the toe rest on the orn'. v

A further object of the invention is to provide an improved support for a lasted shoe so arranged that the last pin is adjustable toward and from the toe rest portion ofthe support'and is automatically locked in adjusted position when'the toe of the shoe is placed upon the toe rest. 'These and other features of the invention includlng important details of construction, and combinations of parts, will be hereinaftermore fully described and claimed.

In the drawings a Figure 1 shows in side elevation a loose nailing machine, together with a work support embodying the present invention;

. Fig 2 is an enlarged view, partly sectional, illustrating the last pin support and toe t; a k i Fig. 3 is a detail; View of the toe clamping button, and the adjustabledevices for supporting it;

Fig. 4 is a cross-section through the work support at right angles to Fig; 2. y

In the illustrative construction, there is provided a loose nailing machine 1 of any well known type but preferably like that shown in the patent to Louis Goddu No. 490,624, granted January 24, 1893, said machine having the usual foot plate 6 and driver 8. A sleeve 10 receives telescopically the horn post 12, herein shown as having its upper portion 14: formed spherical to enter a spherical socket in a block 16. This block supports the base 18 of the toe rest, a dovetail or other sliding joint being provided between the members 16 and 18 to permit longitudinal sliding movements of the toe rest upon its support. Preferably the horn extension 12 carries a rod 20, which is received within a vertical slot formed in a" downwardly extending guide 22, which is rigidly secured to the block 16. The prothe recess being covered by a plate 24 havint; therein a transverse slot adapted to receive a pin or bolt 26,- which is secured to the supporting plate E28 of the toe rest carrier 30, uponv which issupported, in a forwardly inclined position,.a block 32 of rubher or other yielding material to sustain the which likew ise extend s through an aperture toe oi the shoe beingoperated upon.

Secured to the toe rest carrier 30 is a supporting arm having its'upperendportion bent at an inclmationto receive the pad 32 and having a substantially verticalpor-.

tion gfi extending downwardly fromthe pad and a laterally inclined portion provided with a slot 38, the surface of the arm on each side of theslot being roughened or serrated, as shown. The slot 38 receives'a bolt 40,

in a plate carried bya housings-ft, which supports the tubular casing 4601 an adjust able last pin 48. Preferably the housing slides'upon the lower slotted portion of the I ,lin order to accommodate lasts 01"" different lengths,

the slotted portion of the arm unt1l it is arm 34- and frictionall held thereto'by a spiral spring 50 which surrounds the bolt 40. and is confined against the lower surttace of th'e'plate 42 by an adjusting nut 52. In the .construction shown, the last pin d8 and itsv casing; 4!.(5 pivot-ally sustained upon the housing a l; by a pin 54, the lastpin being thereby ti].tal:)le,'and the usual spring may be employed for 'yieldin szly holding the last pin in a forwardly inclined position. Secured to the pin is an arm 56, to the outer end of which is pivoted a rod 58 arranged to carry a slidable locking member 60, for locking the last pin 48' in adjusted position on the supporting arm 34:. Conveniently the lockingmember 60 passes through an aper-- ture in plate 4.2 and has its upper surface provided with serrations frictionally to engage the serrated surface 62 ot the arm 34. Surrounding the outer portlon of the rod 58 isa spring 6 t confined between two thimbles (i6, slidable upon the rod, the outer one oi.

these thinibles being" confined by nut 68 threaded to the rod, and the inner 'thimble bearingagainst the outer face of the locking member 60.

j The construction described provides for an automatic locking device for securing the last. pin in adjusted 'positlon upon the arm.

the last'pin may beadjusted along located at the correct distance from the pad 32 suitable for the last which is to be placed upon the support. lVhen the last is located with its toe portion upon the pad 32 and the pin 48 is inserted in the usual pin socket, the last pin will be tilted rearwardlyv against the force of the spring 64:, thereby raising the locking member 60 and causing it trictionally tofengage theserrated surface 62 and lockthe last pin in itsadjusted position relatively to the toe pad 32. V

The foot plate 6 oil themachine is provided with an extension 70, connected to the foot plate by a sliding joint indicated at 72 which permits lateral movement of the eX- tension. A stem 74 has threaded engagement with an inclined hole formed inthe extension i'O, and the lower portion of said stem is connected by a ball and socket joint 76 with a button 78, whose lower face is shaped to engage the bottom of the toe end portion or a shoe" supported on the pad 82. A set screw -=8O is threaded into an aperture which intersects the aperture receiving the stem 74 and said set screw serves to secure said stem in adjusted position as determined by variations in the characteristics of the work. i

The ball and socket connection between the stein 7 L andbutton 78 provides for a wabbling or universal movement of the button relatively to its stem thereby permittingsaid button to adapt itself automatically to varying inclinations of sole bottoms. "When the shoe is properly positioned upon the support it may be turned by I the operator, and moved laterally as it is being turned, in order to guide it properly with reference to the driver 8, or other work operating instrinnentality as, for example during the operation of inserting reinforcin}; tastenings around the toe portion of a shoe carried by the last. Avery important feature of the invention resides in the pro vision for clamping the toe-portion'ot the shoe'to the toe rest by clamping members co-operatively engaging the shoe and capable of lateral and of turning movements without disturbance or interference with the clamping operation,
